2.2.52.1.11

Unless otherwise stated for the individual organic peroxide formulation, the following definition(s)

shall apply to diluents used for desensitization:

- diluents type A are organic liquids which are compatible with the organic peroxide and which

have a boiling point of not less than 150 °C. Type A diluents may be used for desensitizing all

organic peroxides;

- diluents type B are organic liquids which are compatible with the organic peroxide and which

have a boiling point of less than 150 °C but not less than 60 °C and a flash-point of not less

than 5 °C.

Type B diluents may be used for desensitization of all organic peroxides provided that the boiling

point of the liquid is at least 60 °C higher than the SADT in a 50 kg package.

2.2.52.1.12

Diluents, other than type A or type B, may be added to organic peroxide formulations as listed in

2.2.52.4 provided that they are compatible. However, replacement of all or part of a type A or type B

diluent by another diluent with differing properties requires that the organic peroxide formulation be

re-assessed in accordance with the normal acceptance procedure for Class 5.2.

2.2.52.1.13

Water may only be used for the desensitization of organic peroxides which are listed in 2.2.52.4 or in

the competent authority decision according to 2.2.52.1.8 as being "with water" or "as a stable

dispersion in water". Samples of organic peroxides or formulations of organic peroxides not listed in

2.2.52.4 may also be desensitized with water provided the requirements of 2.2.52.1.9 are met.

2.2.52.1.14

Organic and inorganic solids may be used for desensitization of organic peroxides provided that they

are compatible. Compatible liquids and solids are those which have no detrimental influence on the

thermal stability and hazard type of the organic peroxide formulation.

2.2.52.1.15

Temperature control requirements

Certain organic peroxides may only be carried under temperature-controlled conditions. The control

temperature is the maximum temperature at which the organic peroxide can be safely carried. It is

assumed that the temperature of the immediate surroundings of a package only exceeds 55 °C during

carriage for a relatively short time in a 24 hour period. In the event of loss of temperature control, it

may be necessary to implement emergency procedures. The emergency temperature is the temperature

at which such procedures shall be implemented.

2.2.52.1.16

The control and emergency temperatures are derived from the SADT which is defined as the lowest

temperature at which self-accelerating decomposition may occur with a substance in the packaging as

used during carriage (see Table 1). The SADT shall be determined in order to decide whether a

substance shall be subjected to temperature control during carriage. Provisions for the determination

of the SADT are given in the Manual of Tests and Criteria, Part II, Sections 20 and 28.4.

Table 1: Derivation of control and emergency temperatures

Type of receptacle	SADT a	Control temperature	Emergency temperature
Single packagings and IBCs	20 °C or less	20 °C below SADT	10 °C below SADT
	over 20 °C to 35 °C	15 °C below SADT	10 °C below SADT
	over 35 °C	10 °C below SADT	5 °C below SADT
Tanks	not greater than 50 °C	10 °C below SADT	5 °C below SADT

a SADT of the substance as packaged for carriage

2.2.52.1.17

The following organic peroxides shall be subject to temperature control during carriage:

- organic peroxides types B and C with an SADT ≤ 50 °C;

- organic peroxides type D showing a medium effect when heated under confinement with an

SADT ≤ 50 °C or showing a low or no effect when heated under confinement with an

SADT ≤ 45 °C; and

- organic peroxides types E and F with an SADT ≤ 45 °C.

NOTE: Provisions for the determination of the effects of heating under confinement are given in the

Manual of Tests and Criteria, Part II, Section 20 and test series E in Section 25.

2.2.52.1.18

Where applicable, control and emergency temperatures are listed in 2.2.52.4. The actual temperature

during carriage may be lower than the control temperature but shall be selected so as to avoid

dangerous separation of phases.

2.2.52.2

Substances not accepted for carriage

Organic peroxides, type A, shall not be accepted for carriage under the provisions of Class 5.2 (see

Manual of Tests and Criteria, Part II, paragraph 20.4.3 (a)).

2.2.52.3

List of collective entries

2.2.52.4

List of currently assigned organic peroxides in packagings

In the column "Packing Method", codes "OP1" to "OP8" refer to packing methods in 4.1.4.1, packing

instruction P520 (see also 4.1.7.1). Organic peroxides to be carried shall fulfil the classification and

the control and emergency temperatures (derived from the SADT) as listed. For substances permitted

in IBCs, see 4.1.4.2, packing instruction IBC520 and, for those permitted in tanks according to

Chapters 4.2 and 4.3, see 4.2.5.2, portable tank instruction T23.

Class 6.1 Toxic substances

2.2.61.1

Criteria

2.2.61.1.1

The heading of Class 6.1 covers substances of which it is known by experience or regarding which it

is presumed from experiments on animals that in relatively small quantities they are able by a single

action or by action of short duration to cause damage to human health, or death, by inhalation, by

cutaneous absorption or by ingestion.

NOTE: Genetically modified microorganisms and organisms shall be assigned to this Class if they

meet the conditions for this Class.

2.2.61.1.2

Substances of Class 6.1 are subdivided as follows:

T Toxic substances without subsidiary risk:

T1 Organic, liquid;

T2 Organic, solid;

T3 Organometallic substances;

T4 Inorganic, liquid;

T5 Inorganic, solid;

T6 Liquid, used as pesticides;

T7 Solid, used as pesticides;

T8 Samples;

T9 Other toxic substances;

TF Toxic substances, flammable:

TF1 Liquid;

TF2 Liquid, used as pesticides;

TF3 Solid;

TS Toxic substances, self-heating, solid;

TW Toxic substances, which, in contact with water, emit flammable gases:

TW1 Liquid;

TW2 Solid;

TO Toxic substances, oxidizing:

TO1 Liquid;

TO2 Solid;

TC Toxic substances, corrosive:

TC1 Organic, liquid;

TC2 Organic, solid;

TC3 Inorganic, liquid;

TC4 Inorganic, solid;

TFC Toxic substances, flammable, corrosive;

TFW Toxic substances, flammable, which, in contact with water, emit flammable gases.
